DELIVERY APPARATUS FOR PNEUMATIC DISPATCH SYSTEMS Filed July 2, 1928 2 Sheets-Sheet 2 ATTORNEY S Patented @et. 1, 1929 PATENT OFFICE WILLIAM H. D'INSPEL, or BEL LEnosE MANOR, NEW YORK DELIVERY APPARATUS FOR PNEUMATIC-DISPATCH SYSTEMS Application filed July 2, 1928. Serial No. 290,012.

This invention relates essentially to delivery apparatus for pneumatic dispatch systems in which the cash carriers are dropped into a stationary cylindrical hopper from the terminals of the delivery tubes and distrlbuted to the different operators by means of a vides space for a large number of tubes in a comparatively small area and it facilitates handling of the cash and charge carriers by the operators stationed around the apparatus.

The invention is designed to provide a substantially cylindrical exhaust manifold for diverting the air in front of the moving cash carriers thereby creating a partial vacuum in the delivery tubes and the air sucked in the tubes at the receiving end will propel the 5 carrier to the delivery end of the tube adjacent the hopper.

The invention resides more particularly in the novel combinations hereinafter described and claimed, reference being made to the accompanying drawings in which Fig. 1 represents a side elevation of an apparatus embodying this invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a vertical section of the apparatus.

the line 4.4 of Fig. 3.

In the drawings the numeral 5 designates a number of tubular standards secured to a floor 6 having intermediate horizontal arms or connecting rods 7, upper arms 8 and lower arms 9 radiating from the center. The standards and radial arms constitute a frame of circular formation adapted to take up as little space as possible when installed in a building. A table 10 is supported on the floor by means of a number of posts 11 fastened to the floor. The table carries a number of dispatch tubes with bell shaped or flaring mouths 12 for the insertion of the cash carriers which so are transmitted or returned to the sending Fig. e is a horizontal section taken along or central station. Thetable is preferably circular and room is provided thereon for a plurality of cash tills or charge files which are" positioned opposite to and within reach of the operators sitting on stools 15 located at equal distances apart about the table.

A. vertical shaft 16'is journaled to revolve in bearings formed in the central parts of the upper and lower arms. The shaft is actuated by means of a worm 17 connected to an electric motor 18 supported on a platform 19 suspended from the upper arms. The shaft has secured to it near its lower end a circular disk 20 having an upturned rim 21, best seen in Fig. '3, forming the periphery of the disk.

' The disk is slightly sloped or inclined towards its circumference so that an article placed thereon will roll or slide away from the axis of the disk. The carriers when dropped onto the revolving disk will move by gravitation and centrifugal force towards the periphery of the disk where they can be readily removed by the operators.

An annular guard 22 encircles the rim of the disk and it is secured to the arms or standards so that it will remain stationary. The

guard is substantially L shaped and it covers the circumference or rim of the disk thereby serving to protect" the operators from injury by contact with the rotating outer part of the disk.- Rollers 24: are mounted on the under surface of the disk and they 'coact with a circular track 25 supported on the lower arms. 7 1

Above the disk and fastened to the intermediate arms 7 is located a cylindrical hopper having a conical body 26 so that any article dropped into the hopper will gravitate toward its outlet 27 and drop onto the disk. A series of delivery tubes 28 are p0- sitioned at the upper portion of the hopper and they form a complete circle adjacent the rim thereof. The cash carriers are propelled through these tubes by pneumatic pressure and drop into the hopper. In order to create a partial vacuum in the tubes beyond the advancing end of a carrier a branch pipe 29 connects each of the delivery tubes to a cylindrical tubular manifold 30 secured to the standards. The manifold encircles the upper portion of the hopper and a pipe 31 leading to an exhaust pump is adapted to suck the air from the manifold. The air in the tubes 28 is thereby diverted into the branch pipes 29 and forced into the manifold thus creating a partial vacuum at the inlet terminals of the tubes Where the carriers are inserted and sucked into the tubes. A spring flap valvej32 normally closes the delivery end of each tube but when the carrier reaches the valve it is opened by the impact of the front end of the carrier.

I claim 1. A delivery apparatus for pneumatic dispatch systems comprising a frame, a hopper secured to the frame, a ser es of delivery tubes leading into the hopper, a disk arranged under the hopper, and means for rotating the disk. I

2. A delivery apparatus for pneumatic dispatch systems comprising a frame, a hop per secured to theframe, a series of delivery tubes leading into the hopper, a, tubular exhaust manifold connected to the frame, a branch pipe leading from each tube to the manifold, a disk arranged under the hopper, and means for rotating the disk, 7

3. A delivery apparatus for pneumatic dispatch systems comprising a frame, a cylindrical hopper having a conical tubular body secured to the frame, a series of delivery tubes leading into the hopper, a tubular cylindrical exhaust manifold fixed to the frame, a branch pipe leading from each tube to the manifold, a disk arranged under the hopper, and means for rotating the disk.

4. A delivery apparatus for pneumatic dispatch systems comprislng a frame, a cylindrical hopper having a conical tubular body secured to the frame, a series of delivery tubes leading into the hopper, a tubular cylindrical exhaust manifold fixed to the frame, a branch pipe leading from each tube to thefinanifold, a disk inclined from the axis to its circumference arranged under the hopper, and a motor carried by theframe for rotating the disk.
